[0006]

However, in the above-described conventional pocket structure of the door trim, secondary processing such as welding for fixing is required, and as shown in FIG. In the case where the fitting portions 42 of the mounting pieces 30 of the one and the other pocket body side mounting portions 38, 39 are pushed into the welding pins 35 of the one and the other door trim side mounting seat portions 33, 34 from the side or from above, FIG. As shown by the arrow in FIG. 14, the pocket body 37 was bent, and the pushing operation was difficult and time-consuming, and there was a problem that a reinforcing means for preventing the bending of the pocket body 37 was required.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and a first object of the present invention is to provide a method for welding a member to be mounted to a mounting seat on a mounting member. It is an object of the present invention to provide a mounting structure between members, which eliminates the need for the secondary processing as described above, and allows the mounting operation between the members to be easily performed in a short time.

A second object of the present invention is to reduce the amount of secondary processing such as welding when the pocket body is mounted on the door trim, and to perform the mounting operation easily and in a short time. The object of the present invention is to provide a pocket structure of a door trim for an automobile.

[0009]

In order to achieve the above object, according to the first aspect of the present invention, there is provided a structure for mounting between members, wherein a mounting seat on a mounting member side is attached to a ceiling portion of the mounting member via an upright wall. The mounting piece insertion portion is formed and an insertion opening is formed on the entrance side of the mounting piece insertion portion, and a circular hole is formed in the ceiling portion .
Part and a split groove part extending from the circular hole part to the edge of the ceiling part,
A boss fitting portion including a boss guide portion formed on an edge is formed, and the mounting member is provided with a guide rib portion facing the boss fitting portion.
The attached member is provided with a mounting piece inserted between the ceiling portion and the guide rib portion of the mounting member, and a boss inserted and fitted to the boss fitting portion is projected from the mounting piece. And the mounting piece is inserted between the ceiling portion and the guide rib portion of the mounting member, and the boss is inserted and fitted into the boss fitting portion, so that the mounting member is attached to the mounting member side mounting seat portion. The mounting member side mounting portion is detachably mounted.

With this configuration, the mounting piece of the mounting member side mounting portion is inserted into the mounting piece insertion portion of the mounting member side mounting seat, and the mounting piece is inserted between the ceiling portion and the guide rib portion. The boss can be inserted and fitted into the boss fitting portion, and the mounted member-side mounting portion can be mounted on the mounting member-side mounting seat portion.

[0011] For this reason, when the member-to-be-attached is mounted on the mounting member-side mounting seat, secondary processing such as welding is not required, and the mounting piece is formed between the ceiling and the guide rib. When the boss is inserted into the boss fitting portion while being inserted between the bosses, the tip portion of the boss can be pressed with a finger, so that the mounting operation between the members is easy and can be performed in a short time.

According to another aspect of the present invention, there is provided a mounting structure between members, wherein the mounting member side mounting seat is provided with a ceiling portion provided on the mounting member via an upright wall portion. In addition to forming an insertion portion, an insertion opening is formed on the entrance side of the mounting piece insertion portion, and a circular hole portion and the circular hole are formed in the ceiling portion.
Formed on the ridge and the edge from the edge to the edge of the ceiling
Forming a boss fitting portion comprising a boss guide portion , and
